To afZZ whom, it may concern:

Be it known that I, ViLLI'AM DALTON, of Schenectady, in the county ofSchenectady and State of New York, have invented a certain new anduseful Improvement in Cushioning Appliances for Locomotives, of which imrovement the following is a specification.

he object of myfinvention is to provide means for the prevention of thejars, shocks, and injury to track-rails resultant upon the heavy blowsstruck thereon in the side lurching or abrupt lateral movement oflocomotives when running at high speeds. This destructive action, whileexerted 'to a substantialdegree in the operation of steam-locomotives,is not as great as in the case of electric locomotives, by reason ofthefact that in the former the center of gravity of the machine is abovethe spring suspension, and the springs on opposite sides beingcomparatively close together, as the frames are located inside thewheels, side blows on the railscaused by lurching of the locomotive arein a measure cushioned by the pressure of the locomotive on the spring,which causes a portion of the blow to be expended in downward. pressureon the rail, tlie action being that of. an inverted pendulum. inelectric locomotives the heavy motor-weights are hu ig between thewheels and the center of gravity is below the spring suspension, andunder these'conditions lurching'or abrupt lateral movement of thelocomotive exerts heavy side blows on the rails, which are injurious tothem and to the locomotive.

My invention is designed to so cushion the side blows referred to thatthe impact of the locomotive upon the rail will be reduced to such anextent as to prevent the objectionable results experienced at highspeeds in present practice. y

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a view, partly in section,showing an axle of an electric locomotive, with its Wheels, axleboxes,and pedestal-shoes, illustrating an applicatjon of my invention; Fig. 2,a side view in elevation of a portion of. the locomotiveframe,showin'fan axle-box and wheel; Fig. 3, a horizontal section, on an enlargedscale, through a pair of pedestal jaws, shoes, and an adjacent wheel-hubFig. 4, a similar section,

on a further enlarged scale, through one of the jaws and shoes; Fig. 5,a vertical section through one of the shoes on the line c a of Fig. 3,and Fig. 6 an outer end view in elevation of the shoe.

My invention is -herein exemplified as applied in connection with anaxle 2 of an electric locomotive, upon which wheels 4 are secured andwhich is'journaled in axle-boxes 3 in the ordinary manner. Pairs of llateral flanges 3l and 3 are formed in the axle-boxes, andpedestal-shoes 5e are fitted in the spaces nr side recesses between saidflanges. Each of the shoes 5e is provided with lateral flanges extendingon o posite sides of a pair of vertical pedestal-jaws 5b, fixed on andconstituting part of one of the side frame members of the locomotive,the construction providing for vertical movement of the edestal jaws andshoes relatively to the ax e-boxes and being .as thus far described onewhich is Well known in ordinary practice. v

In the practice of my invention as herein illustrated in structuraldetail, which has been found desirably adaptable in actual service, avertical recess 5f is formed in one of the side flanges of each of thepedestalshoes 5e, and a plate-spring 10, having one or more leaves, asdesired, is fitted in each of said recesses. The ends of the spring 10"or of the outer leaf, if more than one 1s used, bear on seats 5g at theends of the recess 5f, and the middle portion of the sprino or of theinner leaf, if more than one is usedb, bears against the adjacent sideof the pedestal-'aw 5l', as clearly shown in Fig. 5. Sufficient'clearance is left between the side flange of the shoe on the, outsideof the4 roove 5 andthe pedestal-jaw to admit of t e lateral movement ofthe axle-box and shoe and the compression of the spring in resistin suchlateral movement in direction towar it, as most clearly appears byreference to Fig. 4. As

motive construction, the shoes 5'e are interposed between the axle-boxesand pedestaljaws-merely to act as liners or bearing-surfaces for theaxle-boxes, and therefore the location of the springs 1() in the innerflanges of the axle-boxes instead of in the shoes, as in the instanceshown, would not-invo`lve any departure from the spirit and operativeprinciple of my invention.v .Y
